I think we should be prepared, given environmental and political change for large-scale migration. If sea levels rise and 200 million people in Bangladesh and 300 million people in Indonesia need to move, and the entire Chinese seaboard, New York City - that's going to be huge.

Literature helps us transcend ourselves.

Walking is a meditative act. It's so rare that we allow ourselves just to be.

As a child I read all kinds of stuff, whether it was 'Asterix and Obelix' and 'Tin Tin' comic books, or 'Lord of the Rings,' or Frank Herbert's sci-fi. Or 'The Wind in the Willows.' Or 'Charlotte's Web.'

You know, very often, if you look at the kinds of communications that they're getting in an ISIS recruiting video, the videos that, you know, that one hears of as radicalizing them, these are like action movies. And so in the sense, it's that by closing off the idea that young Muslims and particularly young Muslim men can be American heroes, it increases the chance that they'll try to be some other kind of hero. And that, I think, is entirely counterproductive.

Chance plays a powerful role in every life - our brains and personalities are just chemical soup, after all; a few drops here or there matter enormously - but consequences often become more serious as income levels go down.

Novels function and the power of novels function because of their stories.
